Dipole moment order of which of the following pairs of molecules is not conect?

Dipole moment order of which of the following pairs of molecules is not conect?
  1. HF>HCl
  2. H2S>CO2
  3. NH3>NF3
  4. CH4>CHCl3

Solution

CH4 and CHCl3 both have tetrahedral geometry.

But CH4 is non-polar having zero dipole moment and in CHCl3 , Cl is more electronegative than C thus, it will have a net dipole moment greater than CH4.
